Participants

Reaction Steps

A round-bottomed flask was charged with tert-butyl 4-(1-(4-methoxybenzyl)-4-(2-fluoro-4-(1-(4-fluorophenyl)-6-oxo-1,6-dihydropyridazine-5-carboxamido)phenoxy)-1H-pyrazolo[3,4-b]pyridin-3-yl)-1,4-diazepane-1-carboxylate (118.3 mg, 0.1519 mmol), 2,2,2-trifluoroacetic acid (346.4 mg, 3.038 mmol) and CH2Cl2 (10 mL). The reaction mixture was stirred at room temperature for one hour. The solvent was removed and the residue was purified by silica gel chromatography (DCM/7 M NH3 in MeOH from 50/1 to 10/1, v/v) to give product (60.7 mg, 58.88%). LRMS (APCI pos): m/e 679 (M+1).
